Now, take the logarithm of both sides to get $$ -0.693 = -5700k, $$ from which we can derive $$ k \approx 1.22 \cdot 10^.It would be perfect if 1) the initial concentration of C14 were known exactly, 2) the present concentration were known exactly, and 3) the decay of C14 were not counterbalanced by any process introducing new C14.The first problem has caused the greatest difficulties.How am I supposed to figure out what the decay constant is?I can do this by working from the definition of "half-life": in the given amount of time (in this case, hours.
